This should be GP4_2.

Is this needed ?

The ADV7612 has three ports. Ports 0 and 1 correspond to the HDMI inputs, and
port 2 to the digital output. You can leave port 1 out as it's not used on the
board, but you should specify both ports 0 and 2, and add an HDMI connector DT
node connected to port 0 of the ADV7612.
